For the given process instrumentation diagram:

1) What does this PID illustrate and explain the process of each loop of this PID, Explanation includes the feedback system, measurement Parameters, valves, setpoint/manipulated variable if any.

2) Justify the configuration of the control loop which is given (full loop to be considered), ( is it an interactive single variable or compound variable or cascade or multivariable control type? ) and why?

3) Discuss the working principle and applications of the sensors involved in the parameter measurement.
